  • Title: Effects of Rashba and Dresselhaus spin-orbit interactions on the ground state of two-dimensional localized spins.
    Author: Oh JH, Lee KJ, Lee HW, Shin M.
    Journal: J Phys Condens Matter; 2014 May 14; 26(19):196005. PubMed ID: 24762988.
    Abstract:
    Starting with the indirect exchange model influenced by the Rashba and the Dresselhaus spin-orbit interactions, we derive the Dzyaloshinskii-Moriya interaction of localized spins. The strength of the Dzyaloshinskii-Moriya interaction is compared with that of the Heisenberg exchange term as a function of atomic distance. Using the calculated interaction strengths, we discuss the formation of various atomic ground states as a function of temperature and external magnetic field. By plotting the magnetic field-temperature phase diagram, we present approximate phase boundaries between the spiral, Skyrmion and ferromagnetic states of the two-dimensional weak ferromagnetic system.
